- Petrobasal Vein: A Previously Unrecognized Vein Directly Connecting the Superior Petrosal Sinus with the Emissary Vein of the Foramen Ovale
The petrobasal vein, an unknown vein directly connecting the superior petrosal sinus and the emissary veins of the foramen ovale and draining into the pterygoid plexus, can occasionally be identified on cerebral angiography as a variant drainage route from the cerebellum and brain stem veins and/or from the superficial middle cerebral vein.
- Transcranial Doppler Velocities and Angiographic Vasospasm after SAH: A Diagnostic Accuracy Study
A threshold transcranial Doppler mean flow-velocity value that would accurately diagnose ≥ 50% angiographic vasospasm remains elusive.
- Mechanical Thrombectomy for Treatment of Cerebral Venous Sinus Thrombosis in Vaccine-Induced Immune Thrombotic Thrombocytopenia
Anecdotal experience suggests that endovascular therapy may be safe and effective in reducing thrombus burden in selected cases of postvaccination cerebral venous sinus thrombosis.
- 4D Flat Panel Conebeam CTA for Analysis of the Angioarchitecture of Cerebral AVMs with a Novel Software Prototype
4D flat panel conebeam CTA reconstructions allow detailed analysis of the nidal angioarchitecture of AVMs. Further improvements in temporal resolution and automated reconstruction techniques are needed to use the method generally in clinical practice.
